How to Implement an Auto-Reply System Using EmailJS in Your React Project

Setting up an auto-reply system for your React project can significantly enhance the user experience by providing instant feedback when users submit forms. EmailJS is an excellent service for this use case as it enables you to send emails directly from your client-side app without requiring a dedicated backend. In this article, we'll explore two ways to integrate EmailJS into your React project: using the SDK and the REST API.

Prerequisites

1. A React project setup (using Create React App, Vite, or your preferred framework).


2. An EmailJS account. Sign up
   
   
   

   
   
   
   Alternative Method: Implementation Using the EmailJS REST API
   

   
   
   

   
   
   
   Step 1) Install Axios
   

   
   
   

   Install Axios for making HTTP requests:
   
   

   
   
   
   
   

   CODE Kopieren

   npm install axios
   
   

   
   
   
   
   
   
   
   

   
   
   
   Step 2) Create the REST API Integration
   

   
   
   

   Use Axios to send a POST request to the EmailJS REST endpoint:
   
   

   
   
   
   
   

   CODE Kopieren

   import React, { useState } from 'react';
   
   import axios from 'axios';
   
   
   
   const AutoReplyForm = () => {
   
     const [formData, setFormData] = useState({
   
       user_name: '',
   
       user_email: '',
   
       message: '',
   
     });
   
   
   
     const handleChange = (e) => {
   
       setFormData({ ...formData, [e.target.name]: e.target.value });
   
     };
   
   
   
     const sendEmail = async (e) => {
   
       e.preventDefault();
   
   
   
       const payload = {
   
         service_id: 'YOUR_SERVICE_ID',
   
         template_id: 'YOUR_TEMPLATE_ID',
   
         user_id: 'YOUR_PUBLIC_KEY',
   
         template_params: formData,
   
       };
   
   
   
       try {
   
         const response = await axios.post('https://api.emailjs.com/api/v1.0/email/send', payload);
   
         console.log('Success:', response.data);
   
         alert('Email sent successfully!');
   
       } catch (error) {
   
         console.error('Error:', error);
   
         alert('Failed to send email.');
   
       }
   
     };
   
   
   
     return (
   
       <form onSubmit={sendEmail}>
   
         <input
   
           type="text"
   
           name="user_name"
   
           placeholder="Your Name"
   
           value={formData.user_name}
   
           onChange={handleChange}
   
           required
   
         />
   
         <input
   
           type="email"
   
           name="user_email"
   
           placeholder="Your Email"
   
           value={formData.user_email}
   
           onChange={handleChange}
   
           required
   
         />
   
         <textarea
   
           name="message"
   
           placeholder="Your Message"
   
           value={formData.message}
   
           onChange={handleChange}
   
           required
   
         />
   
         <button type="submit">Send</button>
   
       </form>
   
     );
   
   };
   
   
   
   export default AutoReplyForm;
   
   

   
   
   
   
   
   
   
   

   
   
   
   Key Points:
   

   
   
   
   
   
   • The REST API requires a payload containing service_id, template_id, user_id, and template_params.
   
   
   • Replace YOUR_SERVICE_ID, YOUR_TEMPLATE_ID, and YOUR_PUBLIC_KEY accordingly.
   
   
   
   
   

   
   
   
   Reference:
   

   
   
   

   → Email Services tab in the sidebar menu.

   
   
   

   TEMPLATE_ID:
   
   Go to the Email Templates tab in the sidebar menu and click Create New Template.

   
   
   

   PUBLIC_KEY:
   
   Go to

   
   
   

   
   
   
   Customize Auto-Reply Message:
   

   
   
   

   This template is what someone will receive once they submit the form.
   
   

   
   
   

   Note: {{ subject }}, {{ sender_name }}, {{ message }}, {{ email }}, etc. need to match your variable names in your code.

   
   
   

   
   
   
   Conclusion
   

   
   
   

   Both methods provide effective ways to implement an auto-reply system with EmailJS in your React project. The SDK is great for quick setups, while the REST API offers more flexibility for custom implementations. Choose the approach that best suits your project's requirements.
